AIM:to observe the effect of modified surgery of small incision transscleral sulcus fixation of Akreos Adapt AO foldable intraocular lens.

METHODS:The study included 37 patients(37 eyes)who could not be performed the regular implantation of posterior chamber intraocular lens for the rupture of posterior capsule or for the zonular dialysis caused by trauma, congenital or surgery. Bausch & lomb Akreos Adapt AO fordable intraocular lens, VE22000 implantation device were applied in this study. Regular 2.4mm transparent cornea incision and pocket-like sclera incision were made. The intraocular lens were transscleral sulcus fixed by 10/0 prolene suture and the suture was buried within the scleral incision.

RESULTS:The intraocular lenses were all well posited and the postoperative visual acuity(VA)was improved in all patients. Three eyes(8%)were≥0.8 while 18 eyes(49%)>0.4～≤0.6 and the remaining 16(43%)were ≤ 0.4 at 3mo after surgery.Cornea astigmatism was 1.73D±1.22D and 1.62±1.34D before and after surgery, no statistic significance was observed(P<0.05). No severe complication occurred during or after surgeries except for 1 vitreous hemorrhage and 2 cornea edema. There was no suture exposure found.

CONCLUSION:The modified surgery of 2.4mm small incision transscleral sulcus fixation of Akreos Adapt AO foldable intraocular lens has the following advantages such as:good visual results, less postoperative astigmatism, small surgery incision, steady intraocular lens, less manipulation, less complication and more effective.
